Sonoline B Fetal Doppler Video

Why do we recommend 3 MHz probes for fetal heart detection?

Over 90% of OBs, hospitals, and midwives choose 3 MHz probe because they know from the results of millions of exams that 3 MHz works better. It works better because the fetus is so small early in gestation that 3 MHz reflects the ultrasound back to the sensor better than the lower frequency 2 MHz.
A 3 MHz has also been proven to work well throughout the pregnancy.
